G. J. BRYEN ET AL VALVE Filed Dec. l 1921 2 Sheets-Sheet 2 Elli, 1924.

Unire GEORGE J. BRYEN AND RAYMND H. CURRE, 0F DUQUESNE, PENNSYLVANA.

Application filed December To all whom t may concern Be it known thatwe, GEORGE J. Burnin and RAYMOND H. (hinein, citizens of the UnitedStates, and residents of Duquesne, in the count-y ot Allegheny and Stateof ljennsylvania, have invented certain new and useful Yimprovements inValves, or' which the following is a specification.

lhis invention relates to valves for blowing engines, compressors,pumps, and other like machines employed for handling liquids and gases,and incre particularly valves oli' this class employing a valve which isspring supported and spring guided.

lhe principal object of our invention is to provide a valve of thisclass having a novel and improved construction whereby the spring issecurely fastened to a valve plate.

ln the accompanying drawings, Figure l is a vertical sectional elevationof a valve constructed in accordance with our invention.

Figure 2 is a plan View ot the valve seat.

Figure 3 is a plan view of the valve plate.

Figure el is a plan view of the valve spring.

Figure 5 is a plan view of the stop plate.

Referring particularly to the drawings, the numeral 2 designates thevalve seat having a plurality of openings 3. A ring-like valve plate 4is mounted on the valve seat 2 so as to overlie and normally close theports The valve plate a is provided `around its periphery with anintegral upstanding continuous edge or shoulder 5 which has its innertace undercut to form a continuous groove or socket 6.

rllhe valve plate 1l is adapted to be spring supported and springguided, and a coil spring 7 is provided for supporting and guiding thevalve. rlhe spring 7 is preterably formed from a flat plate or disk. Thedisk is cut spira-lly from a point spaced from its outer edge inwardlyso as to form the spring convolutions 8 and provide a continuous outerrim or ring 9.

rThe spring is adapted to be sprung or pressed into the groove or socket6 formed around the valve plate el and is of such a diameter as to litsnugly within said groove and form a rigid connection after being forcedinto place.

stop plate l() is mounted so as to overlie the spring 7 and is providedwith port.

openings ll and a central bolt receiving aperture 1Q.

Vlhe central or small end ot the spring v7 is in the torni ot a circularplat/e or disk 13 and is provided with port openings le adapted to alinewith the port openings ll in the stop plate l0 and also provided with acentral bolt aperture l5. A bolt 16 is passed through the apertures l2and 15 in the stop plate l() and portion 13 ci spring 7, respectively,and through a central aperture 17 in the valve seat 2 and has a nut 18screw threaded thereon to iirmly clamp the stop plate lO, spring 7, andvalve seat 2 together.

rl`he valve plate d may be either machined to form the shoulder 5 or theplate may be spun, forged or otherwise worked tov form the shoulder, asdesired.

lThe feature ofthe invention is the provision or' a continuousattachment for the spring i' around its entire periphery.

lt will be understood that the invention is not limited to the specificvalve construction shown, since various modiiications employing thenovel spring mounting of this invention will readily suggest themselvesto those skilled in the art.

We claim 1* l. ln a valve, a valve seat having a plurality of portstherein, a flat disk-like valve plate mounted on said seat and adaptedto overlie said ports, said valve plate being provided around itsperiphery with an integral upstanding continuous shoulder, said shoulderhaving its inner tace undercut to form `a continuous socket around theperiphgli ery oi said valve plate, a valve actuating coiled springformed of relatively thin dat metal adapted to resist lateral deflectionot said valve plate and provided with a continuous outer riin, saidspring being adapted to overlie substantially the whole area oi saidvalve plate and to have the outer edge ci the riln portion fittedtightly within said continuous socket formed on said valve plate,

2. ln a valve, a valve seat having a plurality of ports therein, a fiatdislnlike valve plate mounted on said seat and adapted to overlie saidports, said valve plate being provided around its periphery with anintegral upstanding continuous shoulder, said shoulder having its innerface undercut to form a continuous socket around the periphtinuous outerrim, said spring being adapted to overlie substantially the Whole areaof said valve plate and toy have the outer edge of the rim portionfitted tightly Within said continuous socket formed on said Valve plate,a stop disk spaced above and over- 1o lying' said spring, and means forclamping said stop disk and said spring to said valve seat.

n testimony whereof, we have hereunto set our hands.

GEORGE J. BRYEN. RAYMOND H. CURRIE.
